A block slides down a frictionless plane having an inclination of 15.6°.
A) If the block starts from rest at the top and the length of this incline is 2.30 m, find the acceleration of the block.
B)What is the block's speed when it reaches the bottom of the incline?

-
net acc down the slope
= g sin 15.6
= 2.64 m/s^2
answer
acceleration of the block.
u =0; s = 2.3
v2 = u2 +2as
v^2 = 0 + 2 * 2.64 * 2.3
v = 3.48 m/s
answer
block's speed when it reaches the bottom of the incline
= g sin 15.6
= 2.64 m/s^2
answer
acceleration of the block.
u =0; s = 2.3
v2 = u2 +2as
v^2 = 0 + 2 * 2.64 * 2.3
v = 3.48 m/s
answer
block's speed when it reaches the bottom of the incline
